[Wine] 32 bit vs 64 bit advice requested

[ToddAndMargo]

Hi All,

I am running Scientific Linux 6.2 (RHEL 6.2 clone) 64 bit.  My version of Wine is:

    $ rpm -qa \*wine-core\*
    wine-core-1.2.3-1.el6.x86_64
    wine-core-1.2.3-1.el6.i686

Really out of date.  Huh?

In order to test out any of the bugs I have posted, I need RPMs of the latest Wine.  There are available by  Dag Wieers at
      http://pkgs.repoforge.org/wine/

Problem.  Dag's RPMs are all 32 bit.  

I do not run any 64 Windows apps (are there even any?).  Is there any reason why I should not remove my x86_64 wine and install Dag's 32 Wine RPMs?

Your advice appreciated.

Many thanks,
-T
