Assuming you have one of the themes in the OP installed, the FCs in the Market app (Vending.apk) are caused by some unknown conflict as a consequence of inverting the Vending.apk to black. Not everyone has this issue (I don't, for instance), but if you do, then here's what I suggest.
Go to the OP for v1.4 (
http://androidforums.com/droid-roms...uilt-source-updated-patch-ota-update-fix.html) and download the v1.4 theme that's consistent with the one you're using for v1.5 (
i.e., the v1.4 Blueberry theme if you're using Blueberry on v1.5). Take the Vending.apk from that theme (which should be themed similarly to your current theme, but not inverted) and replace Vending.apk in /system/app with that Vending.apk. For me, the easiest way to do that is with Root Explorer or with an update zip file.
Make a backup of your current setup first!
Root Explorer Method
Once you've backed up, simply copy the Vending.apk on your SD card, then:
-Use Root Explorer to copy the apk from you SD card
-Go to /system/app/, touch the "Mount R/W" button at the top and touch "Paste" at the bottom
-Long-press on the pasted file, and set the permissions so that all the check boxes in the Read column are checked, only the User checkbox under Write is checked, and nothing is checked under Execute (when you hit okay, you'll see "rw-r--r--" under the app name.
-Touch "Mount R/O" at the top
-Reboot.
Update zip Method
Here's the "cheater's" method of doing an update zip:
-On your PC, take the v1.4 theme file from which you're getting the Vending.apk, right click on it and open it as an archive using 7zip or WinRar (don't ever unzip this file!)
-Inside the zip archive, you'll see 2 folders:
META-INF and
system
-Don't touch the
META-INF folder
-Open the
system folder and delete the
framework folder
-Open the
app folder and delete all the apps EXCEPT Vending.apk
-Close the zip archive, rename it to something like "Non-InvertedBlueberryVending" and put it on your SD card (if you use SPRecovery, then you need to name it update.zip and put it on the root of your SD card).
-Boot into recovery, making sure you've made your backup, then install it as an update zip exactly the same way you would install a ROM or theme
-Reboot.
You should now have a themed non-inverted (normal) Market, which hopefully won't have the issues you're having with the inverted version.
