--- Comment #3 from S silas-wine@flatline.org.uk 2012-06-15 09:01:55 CDT --- One problem with being stuck with WINE 1.1.25 is it is not possible to copy rich text (with bold/italic formatting) even to another WINE application. A later version of WINE is required to do this.
I tried WTL 2011 in WINE 1.5.6 with XQuartz 2.7.2 and ran the application "Clipboard Format Spy" alongside it. When I press Copy in WTL, the Clipboard Format Spy display briefly flickers. If I press Copy repeatedly and rapidly, and watch the CFS flicker carefully, it appears that the Copy command is indeed copying new text to the clipboard, but then something else quickly restores the old text.
If I use CFS to Clear the clipboard, the clipboard stays empty. But then I go back to WTL and press Control-C, and whatever WTL puts on the clipboard is rapidly replaced by the OLD contents of the clipboard. Clearing the Mac clipboard first (cat /dev/null | pbcopy) does not help. (Yes I know that's a useless cat by the way but I'm trying to avoid less-than signs.) However, if I restart the computer to get a clear clipboard then it works OK until I put something on the clipboard.
I tried asking XQuartz to disable pasteboard syncing altogether, result clipboard works OK between WINE applications. So I turn on "Enable syncing" again and try to find which one of the sub-options is causing the problem, and the answer is "Update pasteboard when CLIPBOARD changes". If just that option is on and all the others are off, the problem occurs. If that option is off and any combination of the others are on, the problem does not occur. (Unfortunately, having "Update pasteboard when CLIPBOARD changes" switched off does NOT mean you can press Command-C to copy the clipboard to the pasteboard on demand. Command-C has no effect.)
I tried XQuartz versions 2.7.2, 2.6.3, 2.6.1, 2.6.0, 2.5.3, 2.5.1 and the problem was present in all of these. XQuartz 2.5.0 didn't run on OS X 10.7 (hang on startup).
