I'm getting the following error whenever I change a listbox on Windows 8 64-bit with flygrid version 1.4.0.19 (version on .dll) using .NET framework 2.0 building with x86 profile.  The error pops up about 7 times before going away and happens before the NodeCellChanging event.  Notice the weird character in the error.  Is this something you can reproduce?

Thanks!

Hi zdaily,
Thanks for your exception report,
it is enough to find and fix this problem (weird character - that's name of procedure after obfuscation).
We'll let you know when update with fixes will be available for downloading (usually it takes one day).

Zdaily,
Have you tried the latest version of FlyGrid (just download FlyGrid Evaluation and replace v1.4.0.19 dlls with latest)?
The problem with OnDrawItem has been fixed in 64-bit environment years ago.

I downloaded the evaluation for the latest version and verified that it was fixed in there.  May I e-mail you at support@9rays.net in regards to my questions for this?
