After connecting to our Citrix server via the ICA Web Client (version 10.15 but also an earlier version) and launching our application a couple of our customers get the attached "WIFICA32.EXE - Application Error - The instruction at ... referenced memory at '0x0000000c'. The memory could not be read." error. Both users are running Windows XP - SP2 . We've tried uninstall/ re-install and reboot. The error sometimes occurs slighlty sooner after the application launches than other times, and occasionally not at all. We also tried decreasing screen resolution, to no avail.
