Planner-list Weird planner(?) bug (fixed window size)

Hi,

I'm running planner 0.14.5 on Fedora 15 x86_64, and something really 
weird just happened: as I manually adjusted a task's duration by 
dragging its right size, planner window suddenly changed geometry, and 
got stuck to a size of 2572x498 (?!)

~ planner -g 300x300 &
[1] 20478
~ xwininfo

xwininfo: Please select the window about which you
           would like information by clicking the
           mouse in that window.

xwininfo: Window id: 0x320004e "Unnamed - Planner"

   Absolute upper-left X:  408
   Absolute upper-left Y:  280
   Relative upper-left X:  1
   Relative upper-left Y:  27
   Width: 2572
   Height: 498
   Depth: 24
   Visual: 0x21
   Visual Class: TrueColor
   Border width: 0
   Class: InputOutput
   Colormap: 0x20 (installed)
   Bit Gravity State: NorthWestGravity
   Window Gravity State: NorthWestGravity
   Backing Store State: NotUseful
   Save Under State: no
   Map State: IsViewable
   Override Redirect State: no
   Corners:  +408+280  -620+280  -620-302  +408-302
   -geometry 2572x498+407+253

It doesn't allow me to shrink it, and it doesn't maximize either. I can 
only enlarge it by dragging one of its corners.

My setup is: two monitors with different resolutions, using NVidia 
driver and GNOME 3.0. Combined resolution is 3600x1080:

~ xwininfo -root

xwininfo: Window id: 0x15a (the root window) (has no name)

   Absolute upper-left X:  0
   Absolute upper-left Y:  0
   Relative upper-left X:  0
   Relative upper-left Y:  0
   Width: 3600
   Height: 1080
   Depth: 24
   Visual: 0x21
   Visual Class: TrueColor
   Border width: 0
   Class: InputOutput
   Colormap: 0x20 (installed)
   Bit Gravity State: ForgetGravity
   Window Gravity State: NorthWestGravity
   Backing Store State: NotUseful
   Save Under State: no
   Map State: IsViewable
   Override Redirect State: no
   Corners:  +0+0  -0+0  -0-0  +0-0
   -geometry 3600x1080+0+0

It doesn't look like it's planner's fault, but on the other hand all 
other GTK apps are running just fine.

Any tips on how to workaround this? Does planner save any state info 
(such as window geometry) on a file somewhere? Restarting X session 
didn't do any good.

Regards,

Andre
