Bank Manager V10.0.1.3.06

I have a customer that has recently upgraded from V 7.2.9  to version 10.1.3.06. When importing a bank statement in bank manager a 'loading' icon appears and even after importing the bank statement and going out of the cashbook this does not go away. You either need to close the program or end task for it to stop. They are using the Standard bank cats option. I have tested and get the same results. This morning I completely uninstalled and reinstalled (all users remote onto server) but this did not resolve it.

Any idea what is causing this and how to resolve?

Thanks
