Hi George,

1st, please use either "diff -c" or "git diff" to prepare the patch.
You can even use "git diff" on a files/folders that are outisde of a
git source tree.

2nd, I tried what I think was your patch. I've attached the change I
used, it is outputted with "git diff". I used the x2goclient master
branch (

Unfortunately, it failed to fix the bug. I did not experience any
regressions though.

I tested it on both a Windows XP 32-bit SP3 machine and a Windows 8.1
64-bit machine (with the latest required updates & optional updates
from MS.)

3rd, the username I used was "δοκιμαστικό χρήστη". That is how Google
Translate translated "test user" into Greek. Because it is not easy
for me to type that name into the Windows login prompt, I simply ran
commands like the following to test it:
runas "/user:δοκιμαστικό χρήστη" "c:\x2gobuilds\x2goclient\dist\x2goclient.exe"
