strange wait-for-object event after converting TC12 projectsuite to TC14

Hi there,

after converting projectsuite from TC12.50 to TC14.50 we encounter weird wait for object events on certain keyword actions and code snippets, testlogs show no error nor recoginition warning, but during testrun the tc-indicator shows wait for object for some objects with 1min timeout, which are visible and detected in keywordtests.

anyone similar experiences?
