That could definitely be the case, and I should gather some data on the machines that have had this issue.
Hi,
I would recommend to create a Support ticket via the https://support.smartbear.com/message/?prod=TestComplete form. Support guys may ask you for the information that may help them to find the root of the problem. (Note, that SmartBear considers requests to sign NDA if your company thinks that this is needed.)
Additionally, you may consider to use the Report Generator tool provided with TestComplete (https://support.smartbear.com/testcomplete/docs/testing-with/advanced/tracing-critical-errors/report-generator/index.html) and use it to try to get the stack traces that might help your developers to find the reason of the problem internally. (I don't remember if it is explicitly described in the documentation, but it is possible to start more than one instance of Report Generator and attach them to different applications to get more than one synchronized stack traces if needed.)
