Description of Problem:
After logging into a session on a system that has gone to 'black screen', the sidebar/bottombar areas of XS grow in size--see attached images.

The area increases in size with each iteration of screen-saver=>log in=>restore XS.

The recalc is happening with each cycle, whether or not XS is restored for work between screen-saver events.

NOTE 1: This is on a multi-monitor system. And it's the more usual situation in which the monitors are not the same size.

NOTE 2: 
This subwindow inflation can be undone (with sizes returning to exact normal display) by going from the code/text editor into the layout-xml editor, then going back to the code editor. This requires double-clicking in the 'solution' pane to force a restart of the graphical xml editor tool within its graphical editor mode.

Steps to reproduce the problem:
1. Start XS, leave it in a source code window.
2. Be sure to have the tool-fly ins collapsed in their default positions.
3. Let system go to screen saver then power-saver monitor black-out. 
     (XS can be visible [maxed or normal doesn't matter] or minimized at this point.)
4. Log in, bring XS up if minimized. left-hand and bottom subwindow areas will have increased in size.
5. Let system go back to screen saver/black out.
6. Log in. XS's subwindow areas will have grown more in size.

This repeats as long as you don't force a recalc of the side window areas by starting the graphical xml editor, then returning to the code editor.


Actual Results:
Editor changes dimensions automagically.

Expected Results:
Editor stability.

How often does this happen? 
On my system, it happens every time the screen saver/black out cycle is repeated.
If XS remains minimized during any of these cycles, the growth still happens--so some part of GTK(?) isn't checking for that state.

Additional Information:
Win 7 Ultimate [64b] with NVidia GeForce GTS 240 graphics controller [1Gb dedicated video ram].
Dual monitor: [1] 1920 x 1200 [2] 1680 x 1050 ('True color' 59Hz)

This appears to be a cosmetic problem--nothing seems to fail as a direct result.
However, it might indicate GTK instabilities, particularly in multi-monitor issues.
(Such are not uncommon: on resumption, the Android emulator [along with DOS console windows] also fails to remember which monitor it was originally on--a problem XS doesn't have.)

This seems to be limited to situations in which XS is started and you deal solely with C# within the code editor: the visual layout editor is never started, even if the project reads (source) xml files into [background] editor windows when you load an existing project.
