"Window -> Behaviour" config page causes crash

[stfnm]

PuTTYTray crashes when trying to view the Window -> Behaviour config page. This apparently only happens if the putty.hlp file (from the original putty installation) is present in the same directory.

Sir, I like the cut of your jib. Cheers.

This still happens for me on 0.62.9 64-bit

@jimmys: I believe this is a different crash, which I've fixed as gh-29 (thanks again to @twpol), and will be in 0.62.10.
