Excel Freezes frequently

Hi All,

I have an issue with the excel freeze in our organisation.
Our organisation works on Citrix and the office applications have been upgraded to 2010 very recently.We have both 2003 excel users and 2010 excel users.There is a user who has a problem working on excel 2010 the excel freezes.Excel 2010 works fine for some time and all at a sudden hangs,once its hung it freezes all the other applications
The same file runs properly on the other 2010 systems.The Excel file which hangs are also not of huge in size.

I am unable to get to the rootcause of the issue why the excel freezes or hangs in the middle of the work

It would be great if someone could put some light on it and help me in getting to the root cause of the issue and an answer for the excel hanging

Thank You,

we probably would not be able to view the task manager even,once the excel freezes we have to restart the system connect to Citrix again and the excel starts working again,it works fine for some time and might freeze again.The user says that he uses common excel formulae
