i try make works running out of ideas.

== ensure using same target platform colleague

open preferences > plug-in development > target platform. should have same active target platform definition.

if use running platform active target definition, should have exaclty same eclipse ide installation able compare.

== ensure start application same way

open client product file example:

/<your-app>.ui.swt/products/development/<app>-swt-client-dev.product 

click on synchronize link in testing section in overview tab. (sometime need operation twice).

start application run or debug button in same section.

== test other scout application on computer

to determine if eclipse scout ide installation ok or not, happend when create test application in other workspace? manage start it?

== verify content of target platform

@marko-zadravec suggested verify if not have 2 version of org.eclipse.jface in target platform.

in "target platform" preference page, select active target definition in list , click on edit button.

switch content tab. check if havent 2 org.eclipse.jface bundles.

== reinstall ide

sometimes reinstalling eclipse scout developers quickest solution solve kind of problems (go eclipse downloads page).
