Black bar across the task bar on viewer window

[colwil]

Has anyone experienced the following;

I have a multi monitor setup. Screen 1 is my laptop and screen 2 is a larger 19" screen. They are configured as an extended desktop. The laptop is a HP Compaq 6710b with Windows XP SP3 (32-bit).

Quite often if the remote connection has a larger resolution than my laptop screen I will drag the UVNC viewer window to the second screen and resize the viewer window to full size i.e. 1:1 ratio. As I resize the viewer window by grabbing the bottom right hand side of the viewer window and the viewer window nears full size, the taskbar becomes covered in a blackband. The top edge of the taskbar and start button (approx 4 pixels high) is still visible but underneath the blackband the start button and task bar does not responed if I click on them. If I click on the top 4 visible pixels ofthe start button, it works normally.

If I resize the viewer window to make it smaller so its not quite at full size, reducing the height of the viewer window by roughly the same height as the blackband, then the blackband disappears and as I scroll around the viewer window, and the taskbar/start button is no longer shrouded by the blackband. The blackband completely vanishes.

This has been happening for quite a few versions of UltraVNC, but cant for sure say what version it started happening with.
