I've isolated a serious problem causing LONG (1-5 minute) freezes I was experiencing when running P2ATC V2 with XPlane 12.

The P2A_Link program that connects XPUIPC to P2ATC and the TDS Garmins appear to be incompatible--I can run either the Garmins or P2ATC with P2A_Link, but if I try to run both together in a session I get intermittent long freezes that don't crash the sim, but they make the sim freeze and go unresponsive for prolonged periods of up to around 5 minutes.  I've experienced the same repeatable phenomena on several computers now.

I haven't seen the same behavior with P2ATC V2 and MSFS so far, but I haven't used the TDS Garmins in an MSFS session in a while.

P2A V2 has an alternate "Slow" version of the P2ALink that can be installed.  It runs less frequently and therefore has less of an impact on XP.  You can check that option in Settings and then reinstall the XPLink plugin and it should load the "Slow" version.

V3 doesn't use any plugins and therefore has very little, if any, performance impact on XP.

Thanks--that slow mode module does seem to have solved the problem with lockups when flying a plane equipped with the TDS in XP 12.4.2.  Two flights completed in the Thranda PC-12 + TDS GTN750/650 without freezing.  Will try it on my Intel box later.
