&gt; Maybe the 64-bit version doesn&#x27;t support the Adobe Flash plugin?<p>64bit flash works for me.<p>&gt; The another problem with 64-bit versions is that all the pointers are twice as big.<p>You&#x27;re assuming pointers dominate the footprint. if you&#x27;re seeing crashes due to address space exhaustion that&#x27;s more likely due to large strings&#x2F;blobs of data and not a huge amount of pointers.<p>Or to put it differently, do you really think OOM crashes are preferable to some background applications or memory-mapped files being paged out?
