Problems with the graphical interface, to receive the update 18.5.0.125

Hello everyone.

A few minits ago, I received the last update of NIS. Now when I open NIS, the control panel shown lacks fluidity, and even then flashes empty gray rectangle, which disappears in less than a second. This did not happen before the 18.5.0.125 upgrade. Is this problem serious?...I have to uninstall and reinstall the entire program?

I am using NIS2011 in Windows Vista Home Premium 32 bits,  Pentium dual core, 2G RAM


Greetings
