I have installed on the same PC (my main one) three iterations of TC:
1- The "main" or "work" one, x86 beta 4, lots of plugins, extra progs, toolbars, etc. installed. Location is D:\Program Files\Totalcmd
2- A Lean installation, nearly "pure" x86 beta4 also with few plugins, etc. Use is mainly for testing plugins, etc. Location is: C:\totalcmdx86
3- 64bit 8beta 4 kind of lean also, with all the x64 plugins that I find useful (still missing a lot

wincmd.ini for each is in the program directory with absolute paths. When I upgrade I do it in the following order: 2 first, then 3 and last 1 aka my main installation so being last system (Win7 x64) will have it "registered" for stuff like "open with total commander", etc.
THE PROBLEM: each time I upgrade, all three iterations "pick up" the folder tab configuration of my main installation!!!!, losing the one they had. Even if in their own wincmd.ini the "lefttabs" and "righttabs" are DIFFERENT than those of main (1) installation.
All other individual configurations as per each wincmd.ini are kept. The only bugger is the tabs
Please help? Ideas?
