Overlay disappears on Windowed Fullscreen mode

First of all, congrats for LabCompass. It's amazing !

However I've experienced a very strange behaviour on windowed fullscreen (I've tried all versions, even older ones). Note that it has never worked properly in this mode.

What happens :

Step 1 : I launch LabCompass while PoE is open --> LabCompass opens properly. Step 2 : I just alt+tab to windows, sometimes I open Chrome, sometimes not (I use Win 7 64-bit) : the compass picture disappears completely, or all the interface (compass + icons) disappears. I seems there is a window focus problem. Labcompass is then invisible but still present in the task manager.

I initially thought that the other addons I use were in cause (MercuryTrade, TradeMacro) but in windowed mode, LabCompass works perfectly with or without the other addons.

What I tried :

Run LabCompass as an administrator
Deactivated my antivirus
Deactivated Aero
Deleted Client.txt file --> rebooted PoE --> tested LabCompass again --> same problem

I would be glad to know if there is any fix to this problem, as I Have to run PoE in windowed mode to farm the uberlab :/

Thank you in advance for any tip or idea that could help me solving this,

PS : Minor odd behaviour : if you go backwards in a room that has the same name, LabCompass Planner thinks you are in the previous "same name" room. Travel example :
Estate Walkways (room1) --> Basilica Halls (room2) --> Estate Walkways (room3) --> Basilica Halls (room2) --> Estate Walkways (room1) : LabCompass Planner indicates that you are in room 3.
