Hello Pete,
I have the same problem - everything went smooth under Windows 7, but under Windows 8.1 (completely new installation) HomeSite+ is crashing every 10 minutes to 10+ hours. Mostly it is in connection with C:\Windows\SYSTEM32\ntdll.dll, but sometimes also with C:\Windows\SYSTEM32\msvcrt.dll.
Please keep me informed if you found a solution - I will do the same.
@vishu: Zillions of programs are running fine 5-10-15 years after being discontinued, so this is no helpful remark at all. HS was already discontinued when Windows 7 or Wista came out and was running fine with them.
Best regards,
Rüdiger Graf
