Windows CFM files work correctly; but not on LINUX install

Hello -

I created a CFM web app on a Windows Developer Server Edition. Last night, we moved them to a hosted location company which is using CF8 on LINUX (full license). For the most part, alot of the functions work, but these are completely missing in the installation:

- CFWINDOW ability - does not give an error, but the CFWINDOW or windows.create functions work on Windows - same CFM and they do not work on LINUX.

- FCK Editor does not work

- Various other databind/AJAX components which I feel maybe related to the CFWINDOW issue.

Anyone with any ideas which I can share with the hosting company?

Thanks,

Chris
