Lightroom skips random images when opening many images from Lightroom to Photoshop

When I open many images from Lighroom to Photoshop it seems that Lightroom skips to open random images. I've made sure that all the files I want to open are selected, but still I find a few images missing in Photoshop.

How many is "Many"???????????

Try a Smaller number of "Many".

Around 30-50 images. That's never a problem if I open the same amount from Camera Raw. I want to open all of them since they are "one job" and then batch an Import action of them all. If I have to open them up like 10 at a time, I have to wait sertain times for Photoshop to load and apply the action instead of waiting once.
