Is there a reason Wine does not have its own X11 compatible code the same way that Mozilla or other Free Software applications do?
it's mainly because most of the clipboard related code (I mean part of Wine putting info onto the clipboard) are using the Win32 interface, which means we cannot differentiate between CLIPBOARD and PRIMARY as X11 apps can do. See a thread a couple of weeks ago on this subject.
Basically the buffer wraps around, so if i manually try and resize the window right, the right of the copy repeats the left etc
when you resize what ? the original window or the text you pasted ? whatever I try, I cannot reproduce. did you try with some other destination app than your mail client ? (which wine are you using... this also looks like some bugs that have been fixed more than 6 months ago) A+
