How can I have android reinstall my installed apps after I do a factory reset? I have a nexus one and I installed a bunch of apps on it.

After I do a 'factory reset', I go back to 'Android Market' and I see it is trying to download the apps I installed before. However, all of them are stuck in 'Downloading...' - they do not get installed.

I am on WiFi, so it is not an network issue.

Any idea how to re-install those apps?
In addition to Bryan's answer, you could try going to Settings -&gt; Applications -&gt; Manage applications and clearing the data for the Market.  That might be easier than manually cancelling every download.
