I've searched the most recent 1200 (or so) posts and haven't found a similar problem to mine:
When I open N++ (or take it out of focus), a small grey "window" appears on the page. It has an X in the top right corner. If I click the X, it closes the "window" and the layout of the program window changes. I can restore the layout to its original if I close the new greyed out sections... however it's kind of annoying. It can also lead to Notepad++ crashing.
I also saw this problem before v5.1 was released.
This is hard to explain through words. So here are the web addresses to my screenshots:
Has anyone seen this before? Any ideas as to how I can remedy it?
Windows XP SP2
Which search terms did you use?
I tried (all the words) "x window" and found 52 messages. On the first two pages I found two messages describing a problem similar to yours.
To correct the problem with Hydravision, you can just exclude notepad++ from the application processing. This way you can continue to use Hydravision with other apps.
Open Hydravision properties.
Open Individual Application Settings
Add c:\program files\notepad++\notepad++.exe
You will not be able to switch Notepad from Monitor1 to Monitor2 using the "move to monitor x" option, and full screen will span both monitors.
I wasn't sure what search terms to use... but that sure did it.

It turns out that I have ATI Hydravision running. I know because in the process tab of the Windows Task Manager I found "hydraDM.exe". As soon as I removed it from my running processes, I was able to run Npp without problems.
Now I just need to wade through all the ATI settings to find out how to disable Hydravision permanently...
Don HO and I are trying to get this resolved, but neither of use have ATI cards in combination with a dual monitor setup. Im trying to get a test setup running but if any programmers out there know how t debug this then we'd be grateful :)
