Very slow opening preset file.....

[cousin_itt]

I'm on Win10.
MuLab 8.7.6

If I click on Grid Option, Presets, Open Preset File. It takes 10 seconds to show the folder tree.

I have some mapped network drives in Explorer. When they are offline I get the problem. When they are online there is no problem.

Is there a way to prevent MuLab trying to display the whole of my file system, and just restrict it to a single folder or drive?

[MuTools]

Currently there is no way to exclude specific drives.
