regexDialog problem with Dialog 1.15/1.16

At Line 457 of regexDialog.powerpro included with dialog plugin:

st_hDlg.show("ebFmt", sHide).enable(bEnable)
st_hDlg.show("stFormat", sHide).enable(bEnable)

Has to be changed to:

st_hDlg.show("ebFmt", sHide)
st_hDlg.enable("ebFmt",bEnable)
st_hDlg.show("stFormat", sHide)
st_hDlg.enable("stFormat", bEnable)

Otherwise cannot use the radio selection buttons without this error:
