I've been out in the shop playing with this.  Weird.  If I try scr.get... in a button and display the value in a wx box, it works fine. 

I think something else is saving the jog rate in the ini file after the unload script?  Is that possible?  Here is the setup...

I set the jog rate to 55.  After I exit, the file shows  35.  However, if I get and save that same value under a different key name (Jog for instance), it save correctly every time.  Weird.

--Save Jog Rate % to .ini
local valJogRate = scr.GetProperty("droJogRate", "Value")
local jogSTR = tostring(valJogRate)
mc.mcProfileWriteString(inst, "Preferences", "JogRate", jogSTR)

--the above doesn't work
--added by Tony 10AU21 - axis specific but tey are all the same rate
local cRate = mc.mcJogGetRate(inst, 1)
local cRateSTR = tostring(cRate)
mc.mcProfileWriteString(inst, "Preferences", "Jog", cRateSTR)
The second part works every time, but the first one doesn't. 

Thanks,

Tony (dazed and confused at the moment)

Ironically, I got a reply from AVID today and he told me that this was a known issue.  He suggested the Beta too.  I feel much better that it was not my own stupidity!  Ignorance I can handle... 

I did learn a few things in this quest, so that's good.  Not sure I'll try the beta though.  I may just wait until its released for all.  I'm in the middle of a couple of other projects.  I am curious though. 

Thanks for the help everyone,

Tony
