Editing simulation range not working for TOF on Windows

After opening this dialog on Windows:

nothing can be edited, the buttons don't work & the program hangs. Ouch.

What a pain! The space before the data set name seems to be a problem, but only when the dialog resizes when one tries to click on a edit widget. If the dialog is sized large enough that avoids the problem too. Seems OK now. Sigh.
