Taskbar corrupted/ fonts issues in Vegas 11

Hi everyone,

I have recently upgraded from Vegas 9 to Vegas 11, and here is my strange issue:

The taskbar at the top appears corrupted, as the font used is way too big,
therefore the buttons are overflowing from their placeholders.
In addition, the font used in the menus of said buttons is, on the contrary, way too small, and therefore difficult to read.

I did not have this issue with Vegas 9.

It seems for some reaon that Vegas 11 has issues displaying fonts and buttons in scale with my screen resolution (1920x1080).
I have tried reducing my resolution, to no avail.
I have also installed the latest drivers for my video card (NVIDIA GeForce GTS 250M), to no avail.

Can anyone help me with this issue?

I would really appreciate it.

Thank you.
