Can't enter information into fields
In the last few days I have suddenly found that it is not possible to enter information in some fields. There appears to be no rationale to the problem. It may only be one field in a record, with other fields behaving normally.
These are fields into which it was possible to make entries normally.
Another similar but separate problem is that the cursor does not appear in the field; it is possible to make alterations, but the process is rather erratic. Again the problem is not consistent within a record, with other fields behaving normally.
There is nothing that has been changed in the file.
Is anyone else suffering this problem? Does anyone have any ideas?
