I''ve got a DelphiX app (See previous post). If I alt-tab out of it and then come back, it crashes with the ''Canvas does not allow drawing'' error. Does anyone know a way around this? Thanks, Matt.

I don''t know if this would cause the problem you are descibing, but are you using the TDXForm instead of a normal TForm? (See the DelphiX help and the sample applications for how to use this.)
