We have the problem that looks like this one, but with button components.
It reproduces unstable, and right now we don't know how to describe "steps to reproduce".
But, if you want we will post here or in other topic all info you've mentioned.
Thanks for the information. We have done quite a bit of work on making many actions more stable with respect to these issues. To help your tests, you can consider using "wait for component" to ensure that components are there before clicking them. From the remote control perspective, you can post information here, or open a ticket on which you add information as you get it. It's also be interesting to know the version you're using, what system you're working on etc.
There is one situation which is some like this problem: Execute External Command.When i first execute one external command ,it occured the same mistake. But execute external command offer one more parameter for timeout set. So use this parameter prevent this error. Is there any method to set the time of timeout for Key combination and other actions?
I offered the attachment show the imformance of error while execute Key combination and the properties of the test step. Wish it could be helpful.
