Hi Marco,
I added/changed a few lines in editor.bas in the Files section perhaps you can use it.
It seems that making a file smaller does not make the file on disk smaller.
If the file position is less then the file size the size is kept.
The size property is Read only else it would be possible to make size = position.
I also tried the set window function to get only one button in the taskbar/window but i could not get it work.
Opening the Find window positions the window every time lower.
Regards,
Fred.
