I cannot count how many times I arragned the clips I want, marked down what I do not want, pressed "delete selected clips" and have the entire card being deleted, is this error only happens to me? how can it be fixed?

@desexyvideoclub Hi, it works well on my side. Can you please try with a different card ?

@Manue It happens on all cards, at random, when I try to delete say 5 out of 10 clips, the entire card being deleted instead, which happens at random, I noticed that it is regeistered as double click: "do you want to delete the 5/10 clips? yes? oh now there is 5/5 clips, do you want to delete the 5/5 clips?" in other words, one click is registered as two clicks, I am using windows 7 64 bit
