Should I log support calls for 'minor' quirks?

We went live on Vantage at the start of 2008 and ever since then users
allways get minor quirks in it, such as once a week getting random
errors when closing a screen or walking away from their PC's for an
hour or so and then finding that Vantage has crashed.

We all expect Windows to have the odd problem here and there but should
be same be expected of Vantage ?.

I can imagine that if I logged these quirks as a support call as and
when they happen Epicor wouldn't be that worried about them and they'd
probably be brushed aside, do you all agree ?.
