Anyone else have this PCI E problem?

Ive had many macs over the years and now im starting to see a problem with mac pro's in regards to their pci-e slots. Ive now had several occurrences where a pci e card will wiggle loose and thus cause havoc on my brain until i think of reseating the card. They are nifty and fast but the small footprint of the card seems to be causing this.

you cant hear my inner voice scream... can you..?
