Redmine

When using IE8, I am unable to bulk/batch update on tickets - After right-clicking a single item is selected instead of the multiple items that were checked off before the right-click

Reproduce:

1. Select/Check 2 or more tickets
2. Right click one of the tickets

The ticket that was right-clicked on is now the only selected ticket

Expected results:

1. Select/Check 2 or more tickets
2. Right click one of the tickets
3. All ticket remain selected and context menu appears.

This is how Chrome & Firefox works.
