View available wireless networks window???

Have tried numerous fixes but here is the problem:

Have laptop conected to home wirless network, working fine with full signal strength. EVERY aspect of what normally works is OK. Every time I click onto the 'View available wirless networks' icon either from the tray on the desktop OR through the network connection page (icon) or anywhere else the usual list of available networks wont open.Have checked the driver is OK, and most if not all other config options. Thinking it may be a windows xp problem, but before I re-install the whole thing can anyone shed some light please?

ANY susggestions appreciated.
