Inkscape 0.91 dies if started Maximized w/o file at 1440 x 2560

[Carson Wilson]

If started maximized without an initial file, Inkscape runs erratically, and quietly dies if I move my mouse over the rightmost portion of its maximized window.

If and only if started with no initial file and Default Window Size set to "Maximized," both the 32 and 64 bit versions of Inkscape 0.91 exhibit this issue.

This is under Windows 7 64 bit with my 1440 x 2560 resolution screen. My screen is oriented vertically, so 1440 is horizontal and 2560 is vertical resolution.

I suspect this is related to screen resolution, because both versions start OK if I configure their window size to "Large" instead of "Maximized" (preference setting Interface->Windows->Default Window Size->Large). I suspect memory overflow due to my screen's unusually high resolution, or possibly its unusually high vertical resolution.

Other symptoms:
1. drop down menus appear sized and positioned normally, but only as their right and bottom borders.
2. drop down menus actually work if I click my mouse in the correct region
3. alt-key combinations work - e.g., alt-f-o brings up the open file menu
4. Windows alt-tab can be used to change focus from and to Inkscape's window
5. In this erratic state, if I open a file, a new, smaller Inkscape window appears. Controls are operative, but screen updates are incomplete in a way similar to the original Inkscape window, making the new window unusable.
6. If I start Inkscape by opening a file with it, thereafter it runs reliably even with its window "maximized."

Nothing related to this failure is being recorded in Windows Event Viewer. I will attempt to gather more diagnostics via windbg or similar.

Diagnostics from Inkscape's main (maximized) window captured using Microsoft "Accessible Event Watcher." Notice OBJ_DESTROY occurs just after Location reaches a horizontal value of 50F. I suspect 60 is the threshold value which triggers the failure. When it is reached my mouse pointer is about 90% of the way toward the right edge of my screen. That corresponds to the edge of the page border, see attached screenshot.
