UNSOLVED only one work normal - MMM-Globe and MMM-iFrame

[iMAGiC]

Hi all,
Is there any one knows why two modules configured, will only one work normal.

I have two modules affect each other:
MMM-Globe and MMM-iFrame

Both modules will reload web content by timer setting.

It gets only one module work normal. another one will stop reload. The work one is based on which module is first in to the config.js. The second one (below the first module) will only work once.

If one time only one module, the module works fine, no matter which module.

Any suggest to do? thank you~
