Hey Miller,
I was just checking out your recent commits. The X-paste fix does indeed fix selection click-pasting, but it breaks regular old copy-pasting with in Pd. For example:
1. make an object box with "foo" in it 2. select "foo" and hit Ctrl-C or Edit->Copy 3. create a blank object box 4. hit Ctrl-V or Edit->Paste
Nothing gets pasted. The problem lies in the difference between Tcl's "clipboard" and "selection"; clipboard is Ctrl-C/Ctrl-V and selection is X-paste. Your commit converted [clipboard get] to [selection get]. I think the solution is to revert the X-paste commit and then add separate logic for [selection get] to get X-pasting working.
