Re: [B2-devel] Tex-Edit Plus copy/paste problem in SS and B2 MacOSX

[Ronald P. R. <ron...@xs...>]

I tested the new extension, again in a build with the fix by Alexei  
and in a build without that fix.

The crash with SimpleText is gone. In both builds, the copy/paste  
behaviour is identical with or without the extension loaded, both  
within MacOS and between MacOS and MacOSX, for the applications I  
tested before (Tex-Edit Plus, AppleWorks, and SimpleText). The serious  
problems that were originally reported are solved by Alexei's fix.

The extension offers a solution for a different problem, a problem  
that I did not know existed. It does indeed enable copy and paste  
between MacOS Stickies and MacOSX in both directions (plain text only).
