cocos2d-x-2.1.5 cocos2d-win32.vc2010.sln problems

Hi

I’m using windows xp sp3, vc2010 express and cocos2d-x-2.1.5

Everytime I open cocos2d-win32.vc2010.sln, it shows 「此方案中的一或多個專案未正確載入。如需詳細資料,請參閱[輸出]視窗。」(In English may be:One or more projects in the solution were not loaded correctly. Please see the Output for details.)

And in output window, it shows 「某些與方案關聯的屬性無法讀取。」(Some of the properties associated with the solution could not be read.)

Why will that happen?

Although I can build the 17 projects in the solution successfully in Debug and Release mode, I found there is 6 libs less in Release mode than in Debug mode

Here is the list:
AssetsManagerTest.lib
CocosDragonJS.lib
CrystalCraze.lib
MoonWarriors.lib
TestJavascript.lib
WatermelonWithMe.lib

Therefore I have to copy those libs from cocos2d-x-2.1.5’s Debug.win32 folder to my project’s Release.win32 folder for executing my .exe file

Is this normal?

Or is it due to the “not loaded correctly” thing?

Please help me, thanks a lot.
