Re: Linrad and Tac32

Thanks for that Roger.
I should have remembered it myself :-)
Setting Linrad to "Above Normal" is enough to prevent Linrad
freezing when Tac32 is started.
Time will show whether this also solves the more occasional
freezes, but I suspect it will.

There doesn't seem to be any way to lock in the chosen priority,
without having to set it anew with Task Manager each time Linrad is
Am I missing something here?
