Yep... so far looks good for me as well.

I am still getting the error "Access violation at address 004B418C in module ‘ScreenshotCaptor.exe’. Read of address 00000004." with v3.05.01 of Screenshot Captor.

It seems to occur under the following senario:

1) Start Screenshot Captor while using dual monitors. 
2) Put my laptop to sleep by removing from docking station
3) Awake my laptop using only the laptop screen
4) Put it back to sleep
5) Start my laptop again the next morning in its docking station using dual monitors.

At that point, when I first use Screenshot Captor, I get the error.  It seems to clear itself after that.

Probably should have mentioned in my original post that I switch from a dual monitor environment at work, to using just the laptop screen at home.  Which would be right inline with your comment of "something to do with monitor info changing in sleep mode".
