Invalid Monitor Handle

[idean]

Sometimes (not always) after docking/undocking my laptop from my dual-screen docking station, I get a "Invalid Monitor Handle" popup and the tooltray icon turns red.  My only solution is to exit the application and start it anew, and it works fine then...

I get the exact same problem, might be related to using Remote Desktop on a single-monitor machine to access my dual-monitor machine...

[mouser]

hmm.. very strange. can you describe the actual steps to reproduce?

[sba]

Repro'ed it on my first attempt (dunno if all steps are mandatory):

- took a screenshot of an app on the 1st monitor (actually discarded it in the "what's next" dialog)
- took a screenshot of an app on the 2nd monitor (actually discarded it in the "what's next" dialog)
- connected to the machine using Remote Desktop from another PC that has only one monitor
- closed the Remote Desktop session  (not a logoff!)
- reconnected to the dual-monitor PC's console
- hit Alt+PrtSc
- got the error message ==> had to close ScreenShot Captor

Ok I think i'm narrowing it down.

Can you check for me -- if you repeat that process just do a normal PrtScr to capture the entire screen, do you get the error?
I.e. is it only when you do an alt+PrtScr for active window capture, that the problem occurs?

[sba]

Indeed, I'm not able to repro the problem with just PrtSc

[mouser]

ok hopefully that should be the clue i need to track down the problem, thanks. i should have a sc update this week and we can try to test some fixes.

[sba]

great! just drop a note here to notify me where there's something I can give a shot

I hate to say, but just got the problem again with 3.03.01...

I hate to say, but just got the problem with 3.04.01

[mouser]

I've been so slow getting this latest update out, but i haven't forgotten.  This week for sure.

[mouser]

Well I am having a heck of a time reproducing this -- Can I clarify something -- is anyone ever getting this OTHER than with the use of remote desktop?

Can you try:

I hate to say, but the problem is still there with 3.06.01...

[mouser]

im working on the new sc release as we speak.. i've fixed a couple of other bugs and there's is not much left to do but fix this evil one.

[sba]

if you need a tester for preliminary builds...

[mouser]

Ok I think i have it fixed; new version coming up tonight.

New release is up and official -- hopefully solves the problem.
