Hi Stan,
When I open the program it is almost always in a state of resistance to doing anything - is very sluggish and clicking on a tab might get a result 5 or 10 seconds later if not longer than that, and trying to do anything in the WN History panel is a waste of time. This has been going on for quite some time. It was not resolved by upgrading to Ver 4.5.
However I have now a way to overcome this and it simply involves clicking on the Package, Visual package and Package Winnings tabs in that order and the program immediately frees up.
If there are any error logs I can send will be happy to do so.
Don't know if any others suffer this issue.
