Hi,

I am using VMD 1.9.3 on a Windows 10 computer and I would like to use QwikMD to prepare simulation files. I have done this successfully in the past, but now encounter an error when loading my PDB file.

When I open QwikMD and select my PDB file and click Load, I see the following error:

````
Unable to delete macro ''
Unable to delete macro ''
    while executing
"atomselect delmacro [lindex $macro 0]"
    (procedure "QWIKMD::reviewTopPar" line 8)
    invoked from within
"QWIKMD::reviewTopPar"
    (procedure "QWIKMD::resetBtt" line 217)
    invoked from within
"QWIKMD::resetBtt 2"
    invoked from within
".qwikmd.nbinput.f1.fbtload.btLoad invoke "
    invoked from within
".qwikmd.nbinput.f1.fbtload.btLoad instate {pressed !disabled} { .qwikmd.nbinput.f1.fbtload.btLoad state !pressed; .qwikmd.nbinput.f1.fbtload.btLoad in..."
    (command bound to event)
````

How can I fix this error? I did not change any settings on my computer, so I am not sure how or why this error has appeared. Thank you for any advice.
