Matlab pauses (busy) when executing Audio Precision command

So I have matlab communicating with audio precision software as an object and have the ability to run just about every test that the software has to offer from the matlab command line. There is one test in particular that causes Matlab to be busy i.e I am not able to type anything in the command line because it is working throughout the duration of the test in the AP software. This is not the case for other tests because as soon as I execute the command in matlab the test is run in the AP software, but I can continue running tests from the command window. So I was wondering if there was a way to make matlab execute the command and not wait for this test to complete in the AP software, but rather run like the other tests. The test/command in particular that I am havnig issues with is

APx.MeasurementRecorder.Start()

As soon as I execute this command, Matlab becomes busy while the measurement recorder is running on AP. There should be a list of AP commands that are executable from the matlab window called an AP browser (the version of AP I am on is 3.4). Hopefully I did an ok job of explaining my problem. Thanks for any help in advance!
