I'm currently on 5.0.2.3 and I do NOT want to upgrade unless the upgrade is not going to break anything.

So what have you noticed about 5.0.4.5 that might break or cause me unnecessary problems if I upgrade?

nothing really

Sounds like you have had a lot of problems in the past. I would suggest you back your BI5 up before updating; there are very good instructions on this forum for that. Do you have a particularly sensitive or fragile system ?

I have had no problems with BI5 upgrades since the very early ones, and most of my recent issues were due to Windoze updates breaking things that worked before.
