1) Clicking on a board square at startup can no longer generate a call to playerCanMove before fics exists. 2) Clicking/holding the title bar at startup, before the spellcheck file loads, no longer results in a crash to terminal due to a progressWindow grab attempt before it is viewable. 2a) In the event that another application already has grab, also added catch to the grab call.

'Update idletasks' can be dangerous because it exhibits different behaviors on various operating systems. Generally, it is safe to use after making changes in a window to immediately reflect those changes. However, this approach can also be tricky. Therefore, it is better to avoid its use, especially in a function like 'progressWindow' that is utilized in numerous places. The line that loads the spellcheck files: |

Just a couple quick fixes to some corner cases I ran across.
Clicking on a board square at startup could generate a call to playerCanMove before fics exists, popping up an error message. Fixed by adding a check that .fics exists first, as is done in other places within that file.
Clicking/holding the title bar at startup, before the spellcheck file loads, can no longer result in a crash to terminal due to a progressWindow grab attempt before it is viewable. There were other triggers for this same issue such as occasionally opening a menu at the right moment during startup. Kept hitting this once every so often, prior to adding the update idletasks before the grab.
2a) Finally, added a catch to the progressWindow's grab call. Found that there were still some scenarios at startup where the grab could still fail with "grab failed: another application has grab." For example, on my OS (linux) seemed that highlighting something in the terminal after starting scid would trigger this issue. Outside of startup I could not trigger this particular issue on any other grab calls.
