Mike - What else is running on the PCs. Any bloat ware? Anti-virus packages? Page file active? And so on.
I took the simple way out, my radio PC is a clean build (from MS Disk) so no extras. Running PSDR, VAC, FlDigi and Ham Call. I start Explorer only when I need to fetch new software, Flex and FlDigi updates. I do not let Microsoft (or anybody else) install updates automatically. It solves a lot of problems. My background included performance measurement and planning (in IBM mainframes). I just prefer avoiding excess tasks. 73 Ken AC0HO On Sat, Oct 26, 2013 at 7:16 AM, Michael Ruttenberg <[email protected]>wrote: > Hi all > > Maybe someone can point me in the right direction. > > Using PSDR 2.6.4 with a Flex 3000. > VAC (full version) 4.12 > 4gb RAM Lenovo T420 laptop (with a relatively flimsy Firewire 800 port > installed, new Firewire 400 Expresscard on the way but not yet arrived). > Win7 Pro. > Same issue on Dell Latitude D630 (Firewire 800 port).
