Hi Thaddy, thank you for repply !
The problem is not a name, look:
1) Run the application
2) select a file to open
3) copy the file selected to another, with name 'showing'
4) open and edit 'showing' (sqlite3) (at this point, the app show a graphic of data)
5) close 'showing'
6) go to 2 <--- at this time, on windows, 'showing' is locked by the OS, and the
next FileUtil.CopyFile will fail, if I try to delete 'showing' while the application is open, I get a error message.
On linux, I have no problems.
Thanks !
