Very peculiar problem.
A very peculiar problem have developed in the last day or so.
When trying to select links and click on them, some work, some do not, some only when placing the pointer at the very bottom or top, or the very right or left of the link.
There seems to be no system or logic behind which work and which doesn't. It is confined to no particular website. It appeared out of nowhere and I had done no changes to the system or updates of any kind before. I have since tried updating to FF 6.0 but that didn't help. Neither did a full systems scan for malware find anything.
I am using Vista, and was using FF 5.0, now 6.0.
If anybody has any ideas of what might be the cause and what might be done about it, I would be grateful.
