[Elecraft] Re: Help -- stuck in MCU LD -- SOLVED

[Grant Youngman]

Problem solved, sort of.  Switched to a Windows XP machine, and was  
able to get everything to work.

Same USB/RS-232 interface (Prolific 2303), but obviously not the same  
driver.  So don't know if it is the USB driver (more likely), or the  
Mac version of Utility (probably less likely).

In any case, it worked fine.  I hate to keep one lousy Windows machine  
around for this sort of thing.  Up until this update with 1.1.10.17  
version of Utility, the Mac versions of everything have worked  
swimmingly.
