Message:

• de.ugoe.cs.eventbench.swt.EditSequenceDialog? modified to display long targets in multiple lines. This is a workaround for a problem with tables in Windows (​https://bugs.eclipse.org/bugs/show_bug.cgi?id=259013).

File:

• trunk/EventBenchConsole/src/de/ugoe/cs/eventbench/swt/EditSequenceDialog.java (modified) (10 diffs)
