Application’s tools stop working after opening system menu

[RehnerJD]

Description: if, while working in the application, a combination of keys ‘Alt+Space’ is pressed (opening the application’s system menu), then all of the following tools stop working: Move Tool, Crop Tool, Selection Tool, Brush Tool, Clone Stamp Tool, Eraser Tool, Smudge Tool, Gradient Tool, Paint Bucket Tool, Color Picker Tool, Pen Tool, Shapes Tool, Hand Tool and Zoom Tool.
Actual result: after closing the system menu, the tools stop working.
Expected result: after closing the system menu, the tools work correctly.

Steps to reproduce:

1. Create or open a file.
2. Press Alt+Space to open the system menu and close it.
3. Select a tool and use it (e.g. by pressing left mouse button and dragging the cursor across the screen).
   Defect: any chosen tool is not working unless the application is restarted.

Reproducibility: Always

Severity: Major

Priority: Normal

Symptom: System crash

Workaround: None

Comments: System menu, opened via clicking the left mouse button in the top-left corner of the application window, does not stop the tools from working.
