After having some regression which forced me to revert back to Wine 1.1.24, i have waited for an update to Wine for Slackware. It seems the wait is over when 1.1.26 version has been released on the Sourceforge download page. I take that version and testing it on my desktop.
The regression i had in the earlier version is now gone, and it's getting much much better (mostly are related to application layout and unhanded exception or API).
Let's hope Wine 1.1.27 will not have any more regression like before
