StaffHi Oliver,
There was a similar problem with Developer Express text boxes in an earlier version of TestComplete 7. If you are using a version older than TestComplete 7.52, I recommend that you update to v. 7.52 and check whether the problem persists in this version.
If the problem persists in v.7.52, try using the Keys action instead of setting the value of the 'wText' property. For additional information on the action, see the "Keys Action" help topic. To learn how to modify the recorded On-Screen Action operation that sets a value for the "wText" property so the operation uses the Keys action instead of the property, see the "On-Screen Action Operation" help topic.
