Few users access our Photoshop through Citrix on a mac but use a Windows 7 platform once they're in Citrix. They're all having issues using the Clone Stamp tool. Get the error "Could not use the clone stamp because the area to clone has not been defined (Alt-click to define a source point)". We've reset the clone stamp tool, reset all the tools, and reset the preferences. We've made sure that we're in All Layers. Nothing seems to be working. None of the other forums helped either. Adobe support is no help either.
Thanks,
Moe.
