Error when doing random training

Post by derekadair »

I just purchased the professional version for Windows, so the problem may be the user (me), but I'm running into a reproducible error when performing random training. When I hit the end of a line where I'm playing the color that moves last in the line, I get the following error over and over again (an additional error every second or so): "Training error picking random candidate. (C:\dev\COW Desktop\COW Pro desktop master\EbookForm.pas, line 9365)"

I then have to shut the app down via task manager. or wait for it to eventually crash. I experience this regardless of the book I use. I initially tried with books from my PGNs, but it also had the same issue when using the Demo Book (Sample) as well as a PGN I created from the first game in Fischer.pgn.

I tried reinstalling, but that didn't solve the issue. Happy to provide additional information to help troubleshoot.

For anyone else who may run into this, this does seem to be recorded on the bug list as "Training with the wizard set to Random can cause an infinite loop."

I'm testing an update which fixes a but that happens when training in positions where there are multiple candidates for training side. That isn't common in repertoire situations so it took me a bit to find.

Look for the update in the next few days.
