OS Locks

The OS may lock (Mouse cannot be clicked and mouse doesn't work)
when the device operation (AD/DA Conversion, Counter, Timer) starts. The most reason of OS locking depends on the programming method.
And, the lower processing speed of PC, the easier this phenomenon occurs.

The Sampling Speed is too Fast

For the devices which use virtual memory in the driver, hardware interrupts occur frequently during sampling.
The faster sampling speed, the more frequently this interrupt occurs.
Interrupt occurs so frequently that the use of CPU is monopolized. And the processing of mouse, keyboard and graphic etc. will not be done.
If finite sampling, OS will lock until the end of sampling.
If infinite sampling, OS will lock infinitely.

In this state, please slow down the sampling speed.

The Event Occurrence Interval is too Short

In the sample that events occur frequently, the application lock (Button cannot be clicked and application cannot end) may occur.
This is because the event notifications from driver to application are performed frequently, so that the other events
related to the application (click button, input to the edit box etc.) are not processed.
If finite sampling, other events will be processed until the end of sampling.
If infinite sampling, these events will be processed infinitely.

In this state, please slow down the sampling speed, and make changes
such as restricting the type of using event to increase the occurrence frequency of event.
