How come some apps won't download from Market? I have a rather odd thing happening to three apps in the Market, all free. I tried to install Google Maps and Angry Birds Seasons from the market, but the downloads or installations failed and now I can't download them at all. They both show up under My Apps but rather than the Update or Installed statuses that all other apps in My Apps show, these two show FREE. When I try to install them all goes normally until the message displays saying the download is happening, but it doesn't. The downloading icon appears in the status bar for the briefest moment before disappearing again.

I have Aldiko Book Reader installed and indicating that there is an update available. I believe that the download or install failed when I first tried to update and now the behaviour is the same as described above. I try to update but the download doesn't happen.

I have successfully updated and installed other apps in the meantime. For now it's only those three that are stuck. The initial cause of download/install failure may have been lack of memory but there should be enough memory available now.

I am using an HTC Desire running CyanogenMod-7.0.0-RC2 (Gingerbread 2.3.3). Anyone have any ideas on how to resolve this problem? I've looked at the Market in application management but the clear cache and clear data options are not available.
simple2ext (as described here: http://forum.cyanogenmod.com/topic/20328-solution-to-unable-to-download-big-apps-from-the-market/ ) did the job for me. I am also running CM 7.0.3 and had problems with downloading big apps from market. Sometimes it helped clearing the dalvik cache but not always.
