Dear all, I am using powerdot and ppchtex two draw some chemical structures. Since the new version of hyperref (6.76e), it no longer works. The problem seems due to the order of loading: if ppchetx is loaded before hyperref, I have no troubles. I can freely change the order in report, ... classes but not in powerdot as hyperref is loaded inside the package. Is there any way to force the loading of ppchetx before hyperref without editing the powerdot.cls? The attached files show you a minimal example and here is the file list. I fact, this example compiles fine the first time but when the *.bm is read at the second iteration it does not work except if I load m-ch-en (ppchtex) before hyperref. Below is the list of files. *File List* powerdot.cls 2005/12/10 v1.4 powerdot presentation class (HA,CE) xkeyval.sty 2005/11/25 v2.5e package option processing (HA) xkeyval.tex 2005/11/25 v2.5e key=value parser (HA) article.cls 2001/04/21 v1.4e Standard LaTeX document class size10.clo 2001/04/21 v1.4e Standard LaTeX file (size option) size11.clo 2001/04/21 v1.4e Standard LaTeX file (size option) geometry.sty 2002/07/08 v3.2 Page Geometry geometry.cfg hyperref.sty 2007/05/03 v6.76e Hypertext links for LaTeX hycolor.sty 2007/04/11 v1.1 Code for color options of hyperref/bookmark (HO ) pd1enc.def 2007/05/03 v6.76e Hyperref: PDFDocEncoding definition (HO) hyperref.cfg 2002/06/06 v1.2 hyperref configuration of TeXLive kvoptions.sty 2006/08/22 v2.4 Connects package keyval with LaTeX options (HO ) url.sty 2003/11/24 ver 3.0 Verb mode for urls, etc. hdvips.def 2007/05/03 v6.76e Hyperref driver for dvips pdfmark.def 2007/05/03 v6.76e Hyperref definitions for pdfmark specials graphicx.sty 1999/02/16 v1.0f Enhanced LaTeX Graphics (DPC,SPQR) graphics.sty 2001/07/07 v1.0n Standard LaTeX Graphics (DPC,SPQR) trig.sty 1999/03/16 v1.09 sin cos tan (DPC) graphics.cfg 2001/08/31 v1.1 graphics configuration of teTeX/TeXLive dvips.def 1999/02/16 v3.0i Driver-dependant file (DPC,SPQR) pstricks.sty 2006/01/01 v0.32 LaTeX wrapper for `PSTricks' (RN,HV) pstricks.tex 2006/12/19 v1.15 `PSTricks' (tvz) xcolor.sty 2007/01/21 v2.11 LaTeX color extensions (UK) color.cfg 2001/08/31 v1.1 color configuration of teTeX/TeXLive enumitem.sty 2005/05/12 v1.1 Customized lists verbatim.sty 2001/03/12 v1.5p LaTeX2e package for verbatim enhancements powerdot-default.sty 2005/12/10 v1.4 default style (HA) pifont.sty 2002/09/08 PSNFSS-v9.0a Pi font support (SPQR) upzd.fd 2001/06/04 font definitions for U/pzd. upsy.fd 2001/06/04 font definitions for U/psy. powerdot-default.ps Graphic file (type eps) m-ch-en.sty 2004/07/30 package wrapper for m-ch-en.tex pst-plot.sty 2004/07/15 package wrapper for pst-plot.tex pst-plot.tex 2004/05/18 1.41 `pst-plot' (tvz) m-ch-en.tex nameref.sty 2007/05/02 v2.30 Cross-referencing by name of section refcount.sty 2006/02/20 v3.0 Data extraction from references (HO) testchim2.toc *********** Thanks for your help.
