side panel wont resize

using Crossstudio v2.011

If I have a small width (left) side panel with, say, Project Explorer, then show and subsequently hide the Find panel (to appear over the Project Explorer), the Project Explorer wont resize to a smaller size than the, now closed, find panel.

If I close crossstudio and reopen then it is all ok again, until I repeat the above process. So atleat its not persistent.

This is particulaly annoying if I use my netbook for development - has 1/2 the screen is not project explorer

Any ideas why this happens?

thanks

Mark
