Paul:

Just updated my P3 and K3 to latest FW after both  in storage after a move.  P3 MCU from 1.0 to 1.20.  Have SVGA option installed, but before attaching monitor, noted slowdown of P3 display update.  I've confirmed Nate's feedback that it drops to a crawl at about 150 ms and basically freezes by the time update down to less than 50 ms. (gets slower as rate decreases).  When P3 is at slow update, a power cycle clears the problem and the rate previously selected is now functional.  Is there a configuration parameter that conflicts?  BTW, serial connection baud rate is 38.4 kbps at both P3 and K3.

May also want to revert to MCU 1.09 if that is available.

"Paul,

On a whim I decided to load P3 FW 1.20 earlier this evening and note
that the span adjustment still is much slower than it was in 1.09.  I'd
like to switch back, but I must have deleted 1.09.  I don't see it
anywhere on the FTP server so I guess I'm out of luck.  Bummer.
