My biggest problem has been with inconsistent refreshes and sort orders.
When I click on a volume to show a graph, it looks like it's refreshing data and then shows the graph. However, this is stale data, since the refresh didn't actually pull new data. I've been burned a few times by this. There should be an automatic way of either refreshing on a recurring basis or automatically grabbing the data when a new item is selected.
When I sort a long list (LUNs, voumes, snapshots, etc) by any of the columns, it may or may not actually put them in that order. It also seems to have issues bringing me to either the top of the list alphabetically (if sorted that way), or leaving it on the highlighted volume while sorting the rest - both should be normal GUI design practice by this time. Instead, I'll see a random start point at the top of the list and the scroll bar indicating that I'm at the top, but this often isn't the case. I find myself having to sort, refresh, scroll up and down, and refreshing one more time to make sure the list I see is accurate.
On that note, how about giving us the option for a secondary sort (or defaulting to the last selected sort as the secondary)? I would often like to sort alphabetically by aggregate and then volume or volume and then lun name or by aggregate and free space, and this is impossible with this software. Instead, the secondary sort seems to change each time, so my list may be in different order each time I refresh.
I've been running SM2 on various FF versions from 3-10 on Linux and Windows machines since it was released. It doesn't seem to make a difference which versions/platforms I use; the behaviour is the same. On that note, the last "supported" release of Firefox 6 was released over 6 months ago. When the system automatically updates to a newer version, we can't just revert back with security holes and all just to support this application. Depending on Java and Flash by making SM a web app is nice for supporting other platforms, but it slows down response time for everyone. I find myself using SM 1.1 still because of the bugs and speed issues in 2.0 and R1 (and yes, I've tried the hosts change. It's not super-slow, but it's not nearly as fast as 1.1 was).
