2009-05-19 00:01:24 - weird lines in view screen
This is a problem that I started to notice in leg 5 and in leg 6. Now it has gotten much worse. In the two previous legs it usually showed up as an extension of the land in a wide green line across the screen. On occasion and now in this leg (especially away from land) It shows up as extensions of the course traces of my boat, the lead boat and any other boat selected in the boats tab.
As I zoom in and out the lines jump around and sometimes grow quite large. Zooming in and out definitely causes them to move around and change in width.
This is happening on two different machines, my Vista laptop and my XP desktop. In both FF3.10 and IE 8 on the Vista OS, and FF 3 and IE 7 on the XP OS.
I haven't heard anyone else mention this but it does seem to effect both of my computers, with different OS's and graphics hardware and programs. It is a bit annoying when I'm trying fine tune a course. Any Ideas??

Me too. It mainly happens on the higher magnifications.

Thanks guys for reporting this.

It is certainly more visable during this leg, we know that this bug is there but haven't had the time to work out and implement a fix for it.

We will try to resolve this one soon, Jeroen

Maybe is somehow related to fix for crossing dateline? It first appeared for me during the Leg from China to Rio.

Yes, all these graphic bugs were introduced when we implemented support for datum line crossing. The algorithms actually get a littly tricky when you have vector maps supporting seamsless rotation :) Both me and Jakob currently have a pretty high workload with both our day jobs and SOL and Sailplanner and other things in life - so even though we will fix this it might take a while.

Magical Mediterranean 2026 - Benghazi to Korcula

We return to Antiquity’s Middle Sea for a seventh celebration of all things Mediterranean - fickle winds, history and olive oil.

Red Eye 2026 - Georgian Bay

Welcome to the sensational scenic Georgian Bay of northern Lake Huron, the first area of the Great Lakes to be visited by Europeans in 1615, so former SOLer A2R informed us when he designed this geometrically tortuous course of 317nm criss-cross through its island maze. Originally known as Lake Manitoulin, in 1822 the bay was renamed after King George IV after his succession to the throne. This time we’ll take the very flashy Fareast 31R, which hopefully should keep you wide awake!

Tall Ships 2026 - Stavanger to Aalborg


Welcome to the fourth of four virtual Tall Ships Races in European waters which are concurrently being organized in-real-life by Sail Training International . This fourth race is from Stavanger in Norway into the Skaggerak to a finish off Denmark’s Aalborg and perhaps an Aquavit to toast the adventure afterwards – a final circa 250nm in Sailonline’s classic Clipper 240.
NOTE: Starts and Finishes in tall ships racing are always offshore to avoid conflict with shipping and shipping lanes; online and real-life may not match exactly.

Chinook Salmon - Canada to Andreanovs


A year after spawning in the upper reaches of the rivers of British Columbia, Chinook Salmon develop the age-old urge, so familiar to SOLers, to go to sea, heading for different parts of the northern Pacific Ocean. This race catches up with a particular school with an instinctive memory for the Andreanov Islands far west on the Aleutian Islands chain, as they depart the Salian Sea between Vancouver Island and the San Juans. It’s 2200nm and we’re taking the 60ft Trimaran, in the hope we can keep up!
