Hello Tharmon,
Apologies for the delay in response.
I tried reproducing the issue using your project and the Coded UI test, however I did not receive any "Out of Memory" exception. As checked in Windows Task Manager, I observed memory usage was constant including available memory with slight up and down changes which was expected. Also CPU usage was well balanced some times went till 70% but then dropped back to around 8%.
In order to replicate the issue I increased the loop to 800 clicks, however in this case as well the result were as above. Hence here at my end the memory utilization was balanced with memory released as and when needed automatically.
Testing was done on system with windows 7 ultimate x 32 bit, 2 gb ram machine with the 4.6.20121.678 build of c1Flexgrid.
As per my understanding the issue seems to be specific to the system environment. Kindly provide the same so that I may try and test based on the environment.
Warm Regards,
Rijo
