Dear VMD Developers

It seems that these 2 bugs are in VMD 1.9 beta3 (win32 version):

1) In membrane builder the charmm36 parametrization is not reachable:

 ERROR: Unable to open topology file C:/Program Files/VMD/plugins/noarch/tcl/readcharmmtop1.0/top_all36_lipid.rtf

MOLECULE DESTROYED BY FATAL ERROR!  Use resetpsf to start over.
ERROR: Unable to open topology file C:/Program Files/VMD/plugins/noarch/tcl/readcharmmtop1.0/top_all36_lipid.rtf

MOLECULE DESTROYED BY FATAL ERROR!  Use resetpsf to start over.
    while executing
"topology $topfile"
    (procedure "membrane_core" line 78)
    invoked from within
"membrane_core -l "$uselipid" -x "$xdim" -y "$ydim" -o "$prefix" -top "$useTop""
    (in namespace inscope "::Membrane" script line 4)
    invoked from within
"::namespace inscope ::Membrane {
        puts "membrane_core -l $uselipid -x $xdim -y $ydim -o $prefix -top $useTop"
#        membrane_core -l POPC -x..."
    invoked from within
".membrane.gobutton invoke"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list $w invoke]"
    (procedure "tk::ButtonUp" line 24)
    invoked from within
"tk::ButtonUp .membrane.gobutton"
    (command bound to event)

2) In building graphene, all of the built structures are single layer regardless of specified layer counts.
