ZWO Camera limiting number of frames captured

[Robbie4clearskies]

Hi I have a ZWOASI178 Camera and I noticed tonight that when I select more than 50 frames they are limited. In other words if I select 100 frames to capture, only 63 are captured. For 200, 73 are saved 1000 163, 2000 I think 271, 3000 captured 465.. ( hopefully got that accurate) the numbers are consistent each time. If I select timed exposure no problem. No error messages are reported. I have tried uninstalling and re installing the drvers and ASICAP software with no luck. Is it a software bug? I'm confused. No frames are indictated to have been lost. The % bar moves through to a point then suddenly zips to the end and saves what is there.

Are you using a USB 3.0 port? And do you have enough fast storage space?

The speed of the storage space shouldn't matter, it should still keep going until it has saved the desired number of frames (A while ago I was doing some planetary with an old, slowwww HDD - the software dropped more frames than it saved, but it never stopped capturing until the target number of frames had been saved).
