Here is a simple test for reading and writing presets.
I built an app from this patch and included the preset file in the build.
When I run the app there is no complaint about the preset file. I set a few presets. When I quit the app the preset file is written (I assume from the timestamp - and no complaint in the Max window.) When I run the app the second time there is again no complaint but prefs are not loaded.
The prefs file is being written to the directory where the app resides. I thought in Max 6 the prefs file was written to a different directory as discussed here:
Is there a good comprehensive writeup of the current state of preset handling somewhere? Thanks in advance.
