isv is sort of the hot term for small software developers, it stands for "Independent Software Vendor".
you'll hear the term a lot in reference to "Micro-ISV":

jgpaiva, you're welcome. glad to see that it is useful to you. i'm also learning AHK in the process. btw, the Gui was based from a thread in the AHK forums and the url is in the source..

thanks mediaguycouk, glad you liked it..

The only things I would add are resizable text and text color choice.

good idea, but give me a day or two to add them.

thanks majkinetor's CmnDlg, i've managed to add a standard font display dialog. however i got a little ambitious and decided incorporate something called "relative positioning", which will help you position the OSD in either corner of the screen. of course, you can edit the values yourselves with the INI file. in the meantime, here's a screenshot.

i've posted a new version here with the requested additions. go ahead and give it a try!

A tiny request: Could you please add a "Quit" item to the systray menu?

consider it done..

The positioning thing doesn't seem to have worked well for me. It seems to have chosen the bottom left to be on my secondary monitor rather than the primary.

i need to add some monitor detection code, it seems. for the time being you can delete the INI file & restart the program so that the position will reset to default. but before deleting maybe you can take a peek at the file & let me know the values for these settings: posX & posY.

A tiny request: Could you please add a "Quit" item to the systray menu?

The adjustments are GREAT!

I do have to disagree with the above. I don't want users to quit the program easily. I'm using it to prevent users from muting some important monitoring software. Obviously they were disabling the alarms by muting, now they can disable by killing this program.

There is another issue. Using the systray icon menu you can "Open Volume Control", which opens the system volume window. Selecting Mute All invokes the OSD, but selecting Mute PC Speakers does not.

I would like to see either total removal from the systray or removal of all options from the systray icon. Using the ini file to make all settings changes makes it a little more difficult to disable or change.

Maybe adding a setting in the ini to disable tray, disable settings, etc. Basically add the ability for the tray icon to be disabled and limit display of the tray commands per ini settings.

The problem is that the normal system icon has the "Mute All" functionality. The program icon opens the System Volume Window, which has Mute All and PC Speaker Mute. This gives the users another way to mute the sound. Just being able to remove the program icon would eliminate that ability!

The computers in question are actually television transmitter monitors. The software provides an aural alarm if certain conditions aren't met or readings fall outside a predetermined level. There are also situations where the conditions don't return to normal for hours at a time, which causes the alarm to continue. Often the alarm is muted, but not returned to normal when conditions return to normal. These are the situations I'm trying to prevent without permenantly disabling the ability to mute sound. Hope that makes sense

OSD Mute in the spot light @ freewaregenius... OSD Mute: displays Mute status on the desktop 

It seems to work well, but it gets flagged as a Trojan by lots of the antivirus checkers at Virustotal.com. Any idea why that's happening?

Thanks, jgpaiva. I've never had a problem with a donationcoder.com program, but it's always good to have an explanation. Hope y'all can get it sorted out with the antimalware vendors.
