CTRL-F and CTRL-B don't work

[Periklet]

I'm using Windows Media Center on Windows 7, FLIRC Firmware v2.1, FLIRC GUI v1.1.5 and Harmony 885.

I have the following problem:

In Windows Media Center the keys for back (CTRL-B) and forward (CTRL-F) are not working while viewing a record. When I'm in the program guide the buttons working well, so I'm sure that the buttons are configured correctly. Pushing CTRL-B or CTRL-F on a "normal" keyboard  while viewing a record is working well.

Any idea how to solve this problem?

By the way: The stop button (CTRL-SHIFT-S) is working while viewing a record!

Sorry! I didn't see the previous topic with the workaround:

Using AutoHotkey fixed the problem. Instead "(" and ")" I used CTRL-ALT-F and CTRL-ALT-B...
