Greetings!
My apologies if this is covered somewhere and I missed it.
I have been using your wonderful components since the first one, I think. Around 2005.
Anyhow, I see the suite now contains things I used to pick up elsewhere and integrate into my application.
I have not upgraded in a long time as all is working well and development has slowed down for us… We have bought some enterprise components or suites in the past.
Normally I now develop in Chrome and before Chrome, in Firefox. Some in the organization still use FF. Today, I was checking MSIE and discovered my WIN7 had upgraded to MSIE 10 and I found that the treegrid is slightly broken (columns and headings look like default widths and do not line up) and the Windows do not show my custom color. I use Green in place of your Blue, and now they are White. MSIE 9 still works fine.
Question is (finally! 
is likely that upgrading to 3.6 would fix this?
I believe we are using v.2.5 build 91111
