Crash when exiting application about csvanalyzerpro

[newbiedeveloper9]

Try to use
Application.Exit();
Instead of
Environment.Exit (1);

Tested with the above still crashes I think it's related to having multiple pages opened with large files doesn't seem to crash when having a file open with less then 1000 lines

i sugest then making a global exit function that unloads all the files and then exits
