Panes do not maximize

Hello,

I have Windows 7 installed on a 10-inch screen device. When I first downloaded and installed SmartFTP, there were no problems. However, a month later, the panes (log, folder view, details) do not maximize (image below). I've just updated SmartFTP to latest version and the panes got smaller. I switched between skins but this doesn't help.

Any ideas?

Thanks,
David
