2. My minimized application does not restore when I click on it in my Win'95 taskbar.
3. Are different PowerBuilder and PFC versions compatible with each other?

How can I tell which PFC version I am using?

To determine the PFC Release for a set of PFC PBLs, check PFCAPSRV.PBL(pfc_n_cst_debug)

In PFCAPSRV.PBL(pfc_n_cst_debug)'s instance variables:

Public:
constant integer ici_pfcmajorrevision = 5
constant integer ici_pfcminorrevision = 0
constant integer ici_pfcfixesrevision = 3

or in PFC 6.0

In PFCAPSRV.PBL(pfc_n_cst_debug)'s instance variables:

Public:
constant integer    PFC_MAJOR = 6
constant integer    PFC_MINOR = 0
constant integer    PFC_FIXES = 0

Since these are constants, without even instantiating the debug service, you may use these values anywhere in your application:

ls_version = String(n_cst_debug.ici_pfcmajorrevision) + "." + &
             String(n_cst_debug.ici_pfcminorrevision) + "." + &
             String(n_cst_debug.ici_pfcfixesrevision)

My minimized application does not restore when I click on it in my Win'95 taskbar.

This was a problem that was fixed in PFC 5.0.03.

Window StatusBar Service
Object: pfc_w_statusbar
Method: of_RefreshPosition
Fix: Hide statusbar (disable timer) when the parentwindow is minimized. This allows the window to be restored by clicking on the win95 taskbar. Prior to the fix, the only way to restore a minized PFC app which used the statusbar service was to right click and Restore. Tech support#: 393186

If you are not using PFC 5.0.03 yet, here is the fix:

In pfc_w_statusbar's of_RefreshPositiion( ) function:

if iw_parentwindow.windowstate = minimized! or &
   Not iw_parentwindow.Visible then 
   // Hide statusbar (disable timer) when the parentwindow is minimized or
   // not visible.
   this.visible = false
   Timer (0, this)
   return 1
end if

Are different PowerBuilder and PFC versions compatible with each other?

The  minor revisions of PFC and PowerBuilder are generally independent of each other.  For example you can safely use PFC 5.0.03 with PB 5.0.02. Be sure to do a full rebuild and follow the instructions in the PFC readme files.

You cannot use PFC 6.0 with PB 5.0. PFC 6.0 uses a few PB 6.0 features and is not backwards compatible to 5.0.  You can use the PFC 5.x.xx with PowerBuilder 6.0, but if you went through the trouble of PowerBuilder conversion you might take the extra step and convert the PFC to 6.0 as well.
