Suggestion for ExpressCard to a MacBook Pro

[longshot]

Hi!

I have a MacBook Pro with an ExpressCard slot. I'm looking for a card reader that fits into the slot. I tried this one:

Amazon.com: Slim 17-in-1 ExpressCard Card Reader Writer Adaptor For SD, SDHC, MMC, HS-MMC, MS, HS MS, MS PRO, MS Rom - Fits 34mm and 54mm ExpressCard (Flush fitting inside your ExpressCard slot): Electronics

It fitted well and read the card without problem. But, every time I pull out the memory card the expresscard gets pulled out too. When I first push in the expresscard it clicks in, and then with another push it springs out. But the lock-mechanism (if there is one) is not strong enough to keep the expresscard in while the memory card is pulled out. What are other peoples experience? Is it a problem with the laptop or the expresscard? Does anyone have an expresscard+MacBook for which the expresscard stays in when the memory card is pulled out?

Thanks!
