Sigil is crashing in Windows
 

I was hoping this crashing business would end when I upgraded to 0.7.2 but it didn't. I'm having the same problem so I thought I better post the error:

Error info: Critical:QWindowsBackingStore::flush: BitBlt failed (The handle is invalid.)
Sigil version: 0.7.2
Runtime Qt: 5.0.2
Compiled Qt: 5.0.2
Platform: Windows SysInfo ID 144

Help please.

What version of Windows? What were you doing when it crashed?

This message seems to be the same as reported as a Qt5 bug, but not fixed in 5.0.2 (and no confirmation that it will be fixed) - applications will stop/crash when Windows locks the screen.

The only workaround is to save/exit Sigil before your screen locks.

Windows 7. I opened Sigil, switched to another program, heard some light beeping going on, switched back to Sigil and got the error message. I'm wondering if there's a connection with another program locking up sometimes: Adobe InDesign CS6. The only way out for me is to shutdown and restart in both situations.

Sigil 0.7.2 crashing in Windows 7 64-bit
 

UPDATE: I tried downloading Sigil 0.7.2 on another computer running Windows 7 (both are 64-bit) and I had the same problem. So I'm back to using Sigil 0.6.2 and it's working better (only crashes once in awhile). I'm very disappointed not to be able to use the new features!

something is common to both those systems.
It may be hardware (like a graphics Tablet), A user installed utility (like robo form). Security software... :chinscratch:

Or maybe you did not send a big enough donation :jk:
