Hi All I'm having problems with runnign SD under XP. I've set the system to provid 4096k of EMS as suggested but the program just barfs out after I enter my callsign. Any ideas? tnx Kelvin Crocker M3ZSE/G1ZSE _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963
