IE quirks

[iainc.dev]

Based on past posts (some mine), I updated my SmartGWT libraries to version v8.3p_2014-08-21/PowerEdition Deployment (Full details at bottom.) This solved many IE rendering issues. However, there are a still a few critical ones that remain. Are these issues solved if I upgrade to SmartGWT 5.x libraries (which would be a new purchase and regression testing for us)?

Here are the issues with IE 11 observed. In attached screenshot:

1) the toolbars are too wide. In Chrome/Firefox/Safari, there are normally sized. (See 2nd screenshot).
2) The "Foldres & Files" tab is overlapping with the toolbar. (This could be realted to #1 above.)
3) The treegrid view is not identing correctly. (Again, see screenshot #2 for how Chrome correctly display it.)
4) And most critically: when I select an item in the treegrid view, it does NOT seem to fire the "on click" method. Instead, in order to "trick it", I need to click on the white space that is about 1/2 cm to the right of the item in the treegrid. Then, the "on-click" method fires.

Here's the version of SmartGWT that I have. If there's any other info you need, please let me know:
======================
v8.3p_2014-08-21/PowerEdition Deployment
...
Browser: IE11 on Win7 Enterprise
GWT SDK: 2.5.0rc2
Sun JDK 1.6.0_13
J2EE: Tomcat 6

If your DOCTYPE is set correctly (see FAQ) and your usage is correct, an upgrade should fix the issues, and if it doesn't, the issues could be filed as bugs against 5.x and would be corrected.

If there's some problem with your usage, upgrading won't help obviously.

We're unable to troubleshoot screenshots to tell you whether the underlying cause is an issue with your usage, or issues between 8.3 and IE11 (IE11 was released well after 8.3).
