Default GUI problem in Logic Pro

I build three plugins with WDLTale version. Have a strange GUI problem.

Sometimes Logic Pro does not show GUI if I load multiple plugins. Only the first loaded plugin has GUI. Where's the problem?

I don't know... Does this also happen with one of my plugins, e.g. Kee Bass?

Do you have any static variables set up? These are the same through all instances of your plugin so can have knock on effects like this

Maybe this !?

Code:
IGraphics.cpp:

static BitmapStorage s_bitmapCache;

static FontStorage s_fontCache;


IGraphics.h:

static LICE_IFont* CacheFont(IText* pTxt);


IPlugBase.cpp:

function: void IPlugBase::DumpPresetSrcCode

static bool sDumped = false;

Maybe IPlugAU.cpp code (line 643)
Code:
      if (GetGUI() && IGraphicsMac::GetUserFoundationVersion() >= 677.00) {
don't return the right value on the new versions of OSX!? On the Oli version I see completely different code.

I don't think that's the problem, or else your GUI would never show, right?

In my case, never show. Maybe this is the solution !?

On IPlugAU.cpp file replace the line contain GetUserFoundationVersion() with:
Code:
 
if (GetGUI() && IGraphicsMac::GetUserOSVersion() >= 0x1050) {
And replace the GetUserOSVersion() function from IGraphicsMac.mm with the code from IPlug 2:

Code:
int IGraphicsMac::GetUserOSVersion()   // Returns a number like 0x1050 (10.5).
{  
  static int32_t v;
  if (!v) {
    if (NSAppKitVersionNumber >= 1404.0)
	v = 0x10b0;
    else if (NSAppKitVersionNumber >= 1266.0)
	v = 0x10a0; 
    else {
      SInt32 a = 0x1040;
      Gestalt(gestaltSystemVersion,&a);
      v=a;
    }
  }
  return v;
}
