nal zfd4 hangs / taskbar problems.

Dear all,

We are having an issue om some pc's where we are using zfd 4.0
Mostly these pc's are windows xp.

The problem is always the same. The windows taskbar is flashing,
and the nalicon disappears.

The agent we use is 4.0.26.

Has anyone seen this problem where the taskbar flashes and the nal
agent
disappears?

Thanks
hans
