Current and recent issues:

• May 9th 2026 NOTE: currently Excel documents with pictures (pictograms) can be used, but not saved. When re-opening a document (new or older, irrespective of version) that has recently been saved, an error occurs when opening the file. Files cannot be opend after they have been saved recently. Microsoft seems to have changed picture handling in Excel that causes this error. This issue is fixed in version 5.4 of the CLP mixture classification tool and version 2.4 of the CLP-phrase translation tool. 
• December 2025: Please note to set the Decimal separator in Excel to comma: Go to File, Options, Advanced and uncheck ‘Use system separators’ and set the Decimal separator to a comma. This needs to be done in all versions of the mixture classification tool tool. Since version 5.3 there is a warning if the separator is not set to comma.
