I've been searching for a solution to this problem.
When I execute the program, the splash screen shows up and after that the buddy list should show in the system tray.
Now it doesn't display in the system tray, and no buddy list shows up in the taskbar.
I've checked the option to make sure it always shows in the system tray.
Checking the processes, two programs load.
Pidiginportable.exe and pidgin-portable.exe
Installing another copy of pidgin portable to another folder was a temporary work around I found. I'm hoping there another way to resolve this issue.
I'm on Windows 7 SP 1.
I just install the program to various folders on the computer.
Using pidgin 2.10.6
