Within a customer browse form, I have a sub-form which displays brief summary records linked to the customer. One of the fields on the subform can be double-clicked to open a detail form for that specific record.
This has worked fine for 3 - 4 months. In the last week on the networked version of my system users have noticed that the clickable field on most records is staying blank although it be displayed by mousing over the records. I have not changed the code so I thought this might be due to slow network performance but the data is available at the query which feeds the sub-form and the table or query can be browsed at normal speed.
I ran the system entirely on a local machine but the problem remains - therefore not network or server related. If I run the system on my own machines (ie not on the office network) it performs perfectly as it always did.
Might this be some form of security issue? Does a clickable text box look suspicious to some firewall or other protective software? Any avenues of investigation would be welcome!
