WebDirect Dropping Off Data

Hi all... I have a client that uses WebDirect to enter order data in a portal. They are simply entering a qty, scrolling down, entering another qty etc. During this process when entering and scrolling, some of the data disappears. Eg. They enter 20 but when looking back at the field it only has a 2 in it or it is completely removed. I have tested this myself and it indeed does happen, it is not user error but is not consistent either. I am running a script to validate data on exit but it doesn't touch any fields, just references the Qty field and shows a dialog error if applicable. I have removed this validation on exit and it still happens.

Users are using WebDirect on their local network but other users have reported this over the internet also.

Some of these lists can be quite long and going back to double check your order can be time intensive. 

Has anyone had a similar problem with WebDirect data entry?  

Thanks in advance for your input.
