Single-row taskbar after reboot

[Guest damn-86]

Hey,

some x64-Workstations with XP 64-bit in our company are affected by the following problem:

The users set their taskbar on two rows AND FIXED it. After a reboot the taskbar is reset on a single row. I've searched the internet and the forum but did not find any useful answers.

I already tried to delete the StuckRects2-parameter in the registry. First of all i thought this is the solution. But after 2 weeks the problem appeard again. I deleted the paramater once more. We will see what will happen tomorrow.

Has somebody an idea how to fix the problem?

If any other information are needed, just ask for them. I don't know what information can be useful about this.
