Hi Phil, The programmer is not here today, but to save time I suggest that you already now send a mail to our help desk at waspsupport@dtu.dk Please include the map you are working with in a state where we can see the problem. If you are not able to save the map before the problem occurs, then please send some screen dumps, or maybe a video, so we can reproduce the problem here. Cheers, Morten Good morning Morten, and a happy New Year. Sorry I did not respond sooner. We have our summer holidays here in NZ over the Christmas and New Year period here and I couldn't wait to leave the office and head out into the summer so left my response till now I am back. As per your request, I have sent a word document outlining the problem via screen grabs, and I have also attached the map to this email. I hope to hear from you soon and get back on with my map editing. All the best for 2018. Kind regards, Phil
