Access violation at address 772F8E19 in module 'ntdll.dll'

Post by namgewevets »

Getting an error message when Cumulus is running minimized. I changed the batteries in the weather receiver and checked the USB cable connection. The applications stops running after about 10 seconds when minimized. When I have it running in a normal window there's no problem.

Below is the first section of the bug report. The actual file is attached.

Sorry, I don't know what the cause is, none of my code appears to be involved. But something called 'cwalsp.dll' does appear to be involved:

thread $2420:
772f8e19 +00 ntdll.dll
76cb7885 +0a USER32.dll DispatchMessageW
0091a66d +0d cumulus.exe madExcept CallThreadProcSafe
0091a6d7 +37 cumulus.exe madExcept ThreadExceptFrame
76313388 +10 kernel32.dll BaseThreadInitThunk
>> created by main thread ($1480) at:
07e61524 +00 cwalsp.dll

It appears that's part of something called Content Watch or Net Nanny?
