[Dx4win] DX4WIN Demo Bug

Wed May 27 15:05:07 EDT 2009

Hi Mel,
The Thread error happened right after I tried to save my log , got error message "an exception occured, cannot crfeate file, the system can't find the path" , saved a log with "save as" and then tried to exit. So, it seams these two errors are somehow related. The program did not revert to Demo mode during this event, it happened in another occasion...
So, these three bugs may be mutualy related or not, and depending on same or different circumstances...
Will try to follow Paul's advice to temorarily disable NOD32 antivirus.

73,
Radi F6GNZ

They are different issues Radi. The Demo bug I believe was around in ver 6 also... but it has been a while so I am not sure. The Thread Error I believe is only in ver 7... (at least I never saw it earlier) but I have never heard of it happening unless there is a hardware/configuration issue. I thought it was happening when you tried to write the file. If it is happening on exit, you could create this error if you are using USB devices and turning them off before you exit your program. When the program tries to close the port, it would hang with a Thread Error. Why the program doesn't handle this error more gracefully only Paul could answer.
