Do_PluginIdle never called with kFMXT_ScriptRunning

[Chris Apple]

I wrote a plug-in for Filemaker 10. It controls external hardware during idle processing, Do_PluginIdle.

If I process during kFMXT_Unsafe, it works fine until I disable the plug-in. Disabling the plug-in causes a race condition where Do_PluginShutdown is sometimes called while I'm processing Do_PluginIdle.

If I don't process during kFMXT_Unsafe, it won't work when running a script. I don't ever get PluginIdle with kFMXT_ScriptRunning.
