Solved: unhandleable unidentifiable exception in thread at 0x00000000

I keep getting unhandleable unidentifiable exception in thread at 0x00000000 when I use Xara Web designer.
After that pop up another" Send Error report" with code is sent to Xara.

At first I thought it was due to an old version so I changed it for the newest update.
But no change.
The trouble would start after about a couple of hours, now its five minutes.

I know it could be a software bug but I am also curious if it might be a registry problem.

Any ideas anyone.....its very annoying I can't use the software at all

 

It was the registry at fault. Cleaned it up and now that software is working normally

 

Update....The registry fix did not work. It was a software bug and the workaround is holding down ctrl/alt/shift then hit s. That changes the skin of the program and cures the bug.
